Tissue engineering can perhaps be best defined through the use of a combination of cells, engineering materials, and suitable biochemical factors to improve or replace biological function biomaterials. Biology, Chemistry, Physics, and Engineering are fields of disciplinary applied within tissue engineering; the primary function is to replace, repair or enhance the biological function of diseased and damaged human body parts.
The materials used for the process to restore tissue can be polymer hydrogel, self-assembly, non-woven matrix, Nano-fibrous electrospun matrices, 3D weaving, or any other textile technology-based techniques, depending upon their structural and functional requirements. The market globally is estimated to be 725 billion, growing approximately 10 to 15 per cent per annum. Biomaterial’s application consists of low-tech biomaterial-based prosthetic devices used in the fields of high-tech biomaterials, orthopaedics, dental, drug delivery, cardiovascular, ophthalmology, bone regeneration, wound healing, bio-adhesives, radiotherapeutics and cosmetic surgery. Growth figures from tissue engineering within the cosmetic industry are as high as 10–25 per cent per annum.
